wagon body, andA also for spreading it, which means may be operated by aminimum of power, and will distribute manure overa comparatively largearea.

More specifically it is my Vobject to, provide, at the rear` of themachine, arr-.unloading cylinder having teeth designed to engage themanure and move it downwardly and rearwardly to rake themanure otf ofthe rear end of the wagon body, which unloadings'cylinder is operated atcomparatively low speed,

and which does not have to raise the manure ,while carrying it apartfrom the remainder of the load, and also to provide a'spreading cylinderpositioned to receive lthe manure from the unloading cylinder, andarranged to run at a high speed so that the manure tributed over acomparatively large area.

. A further object is to provide ineans for cleaning the teeth of theunloading cylinder to prevent manure from lodging thereon.

Myinventlon consists in the construction, arrangement and combination ofthe various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, .pointed out in my claimsand illustrated in Figure l shows a side elevation oftheleftside of amanure spreader embodying my invention.

Referring to the .accompanying drawings,

I have used the reference numeral 10 to indicate the wagon body'containing the movable apron 11. These parts are of the ordi-` naryconstruction, and the apron may be .driven in any desired way. Mountedat the rear ofthe wagon body slightly above the movable pron, is anunloading cylinder comprising cylinder bars l2 having teeth 13 therein,the teeth on each bar being spaced apart anequal distance,

andthoseon vone bar being arranged slightlyA on one side of the path ofthose on the adjacent bar, so that the teeth will not'follow in exactlythe same path during their rotation.

On one end of the unloading cylinderis a sprocket wheel 14 driven bymeans of a .sprocket chain l5 connected with a sprocket wheell of thehub of one of the rear wheels. A chain tightener 17 is provided toengage this chain Y provided for throwing the sprocket wheel 16 intoand'out of gear as follows: Securedl to thehub 18 ofthe rear wheel 19 isa ratchet clutchmember 20, and slidin'gly mounted on the rear axle 2l isamating clutch member- 85 22.. Iivoted to the side ofthe wagon body.above the clutch member 22'is a forked rod having its forked endinserted in a groove in the clutchV member` 22. An arm 24 eX- tendsforwardly from the and a link 25- 1s attachedto it. A second link 26A ispivoted to the` -wagon body adjacent to the link 25,'and these two-links are pivotally connected with? each other and with a rod 27, whichrod is pivoted at the 95 forward end ofthe wagon to a crank arm 28` onthe shaft 29, which shaft is controlled by the lever 30. The parts areso arranged in proportion that when the rod 27 is moved rearwardly tothe then the links 25 tially in line, and will hold the vSliding clutchmember firmly in engagement. with the eluttlbi` member that is attachedto the Wheel Info, and when said rodis pulled for- 105 'Wardly, it willcause the sliding clutch mem- -bertpmove to position out 'of engagementv,Witljlthe vclutch on the wheel.

to take up the slack. I have also forked rod 23, l

position shown in Fig. 5,

and 26 will be substan- 'Y vrelative to the center of the unloadingcylinder, and the teeth are spaced apart such -a distance with relationto the teeth n .the unloading cylinder that the teeth on Vthe unloadingcylinder will not engage the teeth This arrangement is clearly shown inFig. 2erl the drawings. The teeth 32 are arranged to run-as close aspracticable to the bars 12, and obviously, if any manure should becomelodged between the teeth 13, it will be dislodged by the teeth 32, andpermitted to drop downwardly. l

I have provided for spreading manure unloaded from the wagon body byvthe unloading cylinder as follows: Supported below and inthe rear of theunloading cylinder is a spreading cylinder comprising bars having teeth36 thereon. The cylinder is fixed to a shaft 37 'which is supported onarms 33 at the rear of the wagon body. The connection is made adjustableby means of the slotted bearing 39 of the ordinary form,

so that the spreading cylinder may be adjusted toward and from theunloading cylinder'.` The teethofthe spreading cylinder are so arrangedwith relation to the teeth on the unloading cylinderthat if'thespreading cylinder should be adjusted .to position where the teeth wouldoverlap those on the unloading cylinder, they will not come intoAcontact therewith'. This arrangement is clearly illustrated in Fig. 2.

I provide for driving the spreading'cylinder as follows: On one end ofthe shaft 37 is a pinion 40, keyed thereto, and rotatably mounted onvthe shaft 37 is an internal gear Wheel 41. Rotatably mounted within theinternal gear wheel 41 are two pinions 42 in mesh with the internal gearteeth, and also in mesh with the-pinion 40. On the -outcr surface of theinternal gear wheel 41 is a small sprocket wheel 42=l which is firmly,fixed to the internal orear wheel 41.l A large sprocket wheel 43 isiixed to the shaft of the unloading cylinder,and connected with thesprocket wheel 4 2*l by means of the sprocket chain 44. By means of thegearing device described, it is obvious that the .internal gear wheel 41will' be rotated at a. higher speed than the unloading cylinder and in adirection with its top moving forwardly relative to the wagon body, andthis movement of the internal gear wheel will be transformed bythepinions and 42 into an increased speed with the upper portion of thecylinder moving rearwardly. I preferably so proportion Athese parts thatthe spreading *cylinder will rotate about twelve revolutions to onerevolution of the unloading cylinder, andsince the teeth of one cylinderslightly overlap those of the other, the s reading cylinder lwill alsoclean the teeth-o the unloading cylinder. l

In practical use, and assuming that the' wagon lbody is loaded withmanure, and the clutch device is thrown into gear, then when the manurespreader is started, the teeth on the unloading cylinder will tearapart, the

adjacent manure and move it rearwardly over the rear end of the apron.It will not require much power to do this. for the reason 'that theunloading cylinder is operated at lcomparatively low speed, and yet itwill unengagement with the cylinder bars and teeth.-

'hence it is customary in the use of said machines to place a partitionbetween the manure and the spreading cylinder when the machine is beingfilled, and to remove this partition when starting the machine. Whenthis is done, little or no manure will be spread by the cylinder untilthe machine hasl been advanced a considerable distance, and the apronmoved rearwardly far enough to bringthe manure against the cylinder. Bythe arrangement herein. shown and described,

'these difiiculties are all obviated. y

In loading myimproved machine, the

manure may be piled (lose to the unloading cylinder, and then thecylinder will begin to rotate .immediately upon the ,advance of themachine, because it takes only a very slight power to move the manuredownwardly and rearwardly under the spreader, ascompared with the vpower required to more it forwardly and upwardly over the top of thespreading cylinder. Furthermore, because in my improveddevice thisunloading cylinder is rotated 'at a/ slow speed, the'inachine may bereadily and easily started with the manure piled close to the unloadingcylinder. During the movement of the manure downwardly and rearwardly bythe unloading cylinder. it will be partly torn apart,

and will be deposited upon the spreading cylinder with all of the largelumps or masses broken apart. Then when this manure strikes upon theforward upper portion ofthe spreading cylinder, it will be torn apartinto very fine particles on account o1 the rapid motion of the spreadingcylinder, and also on account of the fact that the teeth inder at a veryhigh Speed with `comparai lund, to run a cylinder at high speed, which 1nure upon the spreading cylinder, and' then on the` unloadin cylinderwill act as retardi' ing teeth, and t as cci-act with the rapidly gmoving teeth on the spreading'cylinde'r to i' further tear apart andbreak up all of the large particles of the manure..l g

-I am enabled to` operate the spreader cyl tively little power, becausethe manure is discharged upon it in small quantities, and the powerrequired to operate it will be only slightly ,more than the powerrequired to operate a-v balance wheel.

I have Afound by experiment that by the use of my improved machine.manure may be finally separated and spread upon the same spot. at whichthe loaded machine is started in its movement, for thereason that assoon as the machine is advanced, the unloading cylinder immediatelydepositsmazhis manure is thrown rearwardly a consid,- crable distance. v

One of the important features in connection with my improved device, .isthat the lower or spreading 'cylinder is so arranged with lrelation tothe upper one, and to the apron, that it does not at any time come indirect contact with the body of manure on the apron, and hence, it maybe rotated at a high speed without being subjected to the retarding andbinding infiuenee which is the case in connection with spreadingcylinders that come in contact 'with the body of manure. Hence, it mayrun freely and i require very little more power than an ordig narybalance Wheel of similar weight.` It is l practically impossible to getpower enough from the traction wheels of a device of this is in directcontact with the body of manure.

' Hence, by providing'a low speed cylinder to vbe -in contact with thebody of manure, and

to move itdownwardly and rearwardly, and also .a high speed cylinderarranged out of i contact with the manure, but in position to I receivethe discharge from the low speedI cylinder, I attain a result which 1shighly advantageous, for I can remove the manure from the apron witn alow speed cylinder f requiring very little power, andthen spread J itover a wide path with a high speed cylinder that runs without'being indirect contact l with the body of the manure.

Having thus described my invention, what i I claim and desire to secureby Letters Patent of the United States, therefor, is-
